SKIP-BUCKET GAR-LOADING APPARATUS.

Application filed 15, 1925. Serial No. 30,455.

To all whom it may concern:

Be it known that I, WI LIAM E. HALE, a citizen of the United States, residing at Fort Vashington, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Improvement in Skip-Bucket Car-Loading Apparatus, of which the following is a specification.

The principal object of the present inven tion is to provide for keeping the car at rest in loading position while the bucket completes its dumping movement although the car and bucket are operated by the same winding machine, and, generally stated, this, according to the present invention, is accomplished by the introduction of loss motion in the cable which actuates the tram car.

The invention also comprise the improve ments claimed at the end hereof but the invention will be first described in connection with the single figure of the accompanying drawing which illustrates somewhat diagrammatically apparatus embodying features of the invention.

In the drawings 1 is a skip hoist, and 2 is a tran'i car loadable by the skip hoist or, more accurately. by the skip bucket 3 thereof. t is a winding machine for operating both the car and hoist. 5 is a skip hoist cable. 6 is a tram car cable. The tramway 7 may be horizontal or inclined, and 8 is a block for arresting the car 2 in loading position. 9 and 10 are movable pulley weights arranged at opposite ends of the travel of the car and of which one, 10, is lifted and the other, 9, lowered to provide loss motion in the car cable when the car is blocked, the winding machine is in operation, and the bucket 3 is rising to complete the dumping operation. 11 are guide pul leys over which the car cable runs. The movable pulley weights are take-up devices in the sense that they take up and restore slack to the car cable.

not limited as to those matters or otherwise than as the prior art and the'appended claims may require.

I claim:

1. Skip bucket car loading apparatus including a skip bucket, a car,-a winding machine having a skip bucket cable and a car cable attached at its ends to the car, means for arresting the movement of the car in loading position, and take-up devices 00- operating with the car cable and of which one is operative between one end of the car and the winding machine and of which the other is operative between the other end of the car and the winding machine whereby the latter'may operate both the bucket cable and the car cable while the car is at rest in loading position.

2. Skip bucket car loading apparatus including a skip hoist, a tram car loadable by the skip hoist, a winding machine for operating both the car and the hoist, a skip hoist cable, a tram car cable, means for arresting the car in loading position, and mov able pulley weights arranged at opposite ends of the travel of the car and of which one is lifted and the other lowered to provide lost motion in the car cable when the car is arrested and the skip hoist is rising.

In skip bucket car loading apparatus a tram car, a winding machine, a car cable Wound and unwound by the machine and having its ends attached to the car, and a take-up device in each reach of the cable between the car and winding machine.
